April is Adenomyosis Awareness Month. Now is the perfect time to shed light on a condition that’s often misunderstood, underdiagnosed and overlooked. If you’ve ever experienced painful, heavy periods that seem “just normal,” it’s worth knowing about adenomyosis and what it could mean for your health and well-being.

For many women, severe period pain or heavy bleeding is normalised or dismissed. However, in some cases, these symptoms may be linked to an underlying gynaecological condition such as adenomyosis.

What is Adenomyosis?

Adenomyosis is often compared to Endometriosis because the two gynaecological conditions share some similarities. However, there are important differences between them.

Adenomyosis occurs when the lining of the womb (the endometrium) begins to grow abnormally into the muscular wall of the womb (the myometrium). During the menstrual cycle, this tissue behaves like the normal uterine lining (thickening, breaking down and bleeding) but because it is embedded within the muscle layer of the uterus, it can cause inflammation, swelling and pain.

Endometriosis, on the other hand, occurs when tissue similar to the endometrium grows outside the uterus, such as on the ovaries, fallopian tubes or other pelvic organs.

While adenomyosis is confined to the uterine wall, its impact can still be significant and for some women, severely disrupt daily life.

Signs & Symptoms of Adenomyosis

Adenomyosis exists on a spectrum when it comes to symptoms. Some women may experience no noticeable symptoms (asymptomatic), while others experience debilitating pain that disrupts everyday activities including work, exercise and social life.

The severity and combination of symptoms can vary widely, but some of the most common signs include:

• Heavy or Prolonged Periods (menorrhagia): Periods that last longer than usual or involve soaking through pads or tampons quickly.
  
  
• Painful Periods (dysmenorrhea): Severe menstrual cramps that may worsen over time or do not improve with standard pain relief.
  
  
• Pelvic Pain: Persistent pain or aching in the lower abdomen that may intensify before or during menstruation.
  
  
• Pelvic Pressure or Bloating: A sensation of fullness, heaviness or swelling in the lower abdomen.
  
  
• Irregular Bleeding: Spotting or bleeding between periods may occur. 
  
  
• Painful Intercourse: Some women may experience discomfort or deep pelvic pain during sex.
  
  
• Painful Urination or Bowel Movements: This may occur particularly during menstruation. 

What Causes Andenomyosis?

Like many female conditions, the exact cause of Adenomyosis is not understood. However, research suggests that several biological and hormonal factors may contribute to the development of the condition.

While the precise trigger remains unclear, certain factors may increase the likelihood of developing adenomyosis, including:

Age

Adenomyosis is most commonly diagnosed in women between the ages of 35 and 50, although it can occur earlier.

Childbirth

Women who have had children appear to have a higher risk of developing the condition. Pregnancy may alter the uterine lining or the boundary between the endometrium and the muscle layer of the uterus.

Previous Uterine Surgery

Procedures such as caesarean sections or fibroid removal may increase the risk. One theory suggests that something may go wrong during the healing process, allowing endometrial tissue to grow within the myometrium.

Adenomyosis Diagnosis

Diagnosing adenomyosis can sometimes be challenging because its symptoms often overlap with other gynaecological conditions, particularly Endometriosis and Uterine Fibroids. For many women, this can mean experiencing symptoms for years before receiving a clear diagnosis as there is no single test to confirm it.

Historically, adenomyosis could only be definitively confirmed after a Hysterectomy, when the uterine tissue was examined under a microscope. However, advances in imaging techniques now allow many cases to be diagnosed without surgery.

Physical Exam

Typically, the process begins with a medical history and pelvic examination. A healthcare provider may ask about menstrual symptoms, pain levels, and changes in bleeding patterns. During a pelvic exam, the uterus may feel enlarged or tender which can sometimes indicate adenomyosis.

Ultrasound

The next step is usually a transvaginal ultrasound to check for signs of adenomyosis. Ultrasounds are quick and easy tests. This allows doctors to examine the uterus more closely and look for changes in the thickness or texture of the uterine muscle that may suggest adenomyosis.

MRI

In some cases, a Magnetic Resonance Imaging (MRI) scan may be recommended. MRI provides more detailed images of the uterus and can help distinguish adenomyosis from other conditions with similar symptoms.

Because symptoms vary widely from person to person, diagnosis often involves ruling out other conditions and building a full picture of a patient’s symptoms, medical history and imaging results.

If you’re experiencing persistent heavy periods, severe menstrual pain or unexplained pelvic discomfort, it may be worth discussing these symptoms with your healthcare provider to explore whether adenomyosis or another underlying condition could be the cause

Treatment & Management Options

There is no universal treatment for adenomyosis, but there are several ways to manage symptoms and improve quality of life. Each approach should be personalised based on the severity of symptoms, age and reproductive goals.

Medications

Pain relief options, such as over-the-counter anti-inflammatories like ibuprofen, can help manage menstrual cramps and pelvic pain. Hormonal therapies, including birth control pills, hormonal IUDs or other hormone-based treatments, may also be used to reduce heavy bleeding and regulate menstrual cycles. These treatments work by keeping the uterine lining thin throughout the month, which can reduce or even prevent the endometrium from shedding during your period.

Medical & Surgical Intervention 

Not everyone with adenomyosis will require surgery, but in more severe cases, medical or surgical interventions may be considered. One option is uterine artery embolization, a procedure that reduces blood flow to affected areas of the uterus, helping to relieve symptoms such as heavy bleeding and pain. In more advanced cases, a hysterectomy may be recommended as a definitive treatment for women who no longer wish to have children.

Lifestyle Support

A holistic approach to lifestyle can play an important role in supporting overall well-being for adenomyosis. Following an anti-inflammatory diet, rich in omega-3 fatty acids, leafy greens, berries and whole grains – may help reduce inflammation and menstrual pain, while limiting processed foods, sugar and excess red meat can also be beneficial.

Incorporating gentle exercise such as yoga, walking or swimming can improve blood flow, reduce bloating and ease discomfort. 

Managing stress is equally important, as it can exacerbate pain and hormonal imbalances, techniques like meditation, deep breathing or journaling may help.

Additionally, certain supplements including calcium, magnesium, vitamin B6 and antioxidants, may support symptom relief by helping to reduce inflammation and muscle cramping.

Know Your Body & Advocate for Yourself

Adenomyosis may be common, but it is often misunderstood and underdiagnosed. Awareness is the first step toward better care, early diagnosis and effective symptom management.

If you notice persistent heavy periods, severe cramps, pelvic discomfort or other unusual menstrual symptoms, don’t dismiss them as “just part of being a woman.” Speak with your healthcare provider and ask the right questions. Early intervention can make a big difference in improving your quality of life.

Remember: your pain is valid, your symptoms matter and you deserve care that listens and responds. Taking small steps like tracking your cycle, adjusting lifestyle habits and exploring healthcare support can empower you to take control of your reproductive health.
